CLEMENT PHILIBE-RT, EMILE PERREAU, AND ANDR LABORDE, OF PARIS, FRANCE.

MACHINE FOR DECORTICATlNG RANIIE.

SPECIFICATION forming part of Letters Patent No. 514,494, dated February13, 1894.

Application filed March 28, 1893. Serial No. 468,088. (No model.)Patented in France May 3, 1892, No. 221,348, and in England September13, 1892,No.16,398.

Be it known that we, CLEMENT PHILIBERT, hanna Panneau, and ANDR LABORDE,all citizens of the Republic of France, residing at Paris, France, haveinvented certain new and useful Improvements in Machines forDecorticating Ramis, (for which patents have been granted to us inthefollowing countries: France, dated May 3, 1892, No. 221,348, andEngland, dated September li3, 1892, No. 56398,) of which the followingis a specificaion.

Qurinvention refers to improvements in machines for decorticating ramie(Urtica utilis) and the like wherein the librous plants or grass arepassed through feeding rollers, sub- Jected to a crushing action betweentwo opposed undulated or corrugated surfaces of breakerswhich arerapidly brought together and separated, after which the materials arepassed between opposing star section rollers to remove the broken woodyparts, and finally carried by delivery rolls onto an endless band.

Qur invention will be readily understood by reference to theaccompanying drawings.

Figure 1 is a front elevation of a machine according to onrinvention,Fig. 2 being a view of one of the sides, and Eig. 3 showing the otherside. Fig. a is a transverse section through the line a h of Fig. l. Themachine is composed of a double cast iron frame A connected by crossbars, the said frame carrying at its upper part grooved cylinders CC fordrawing or feeding into the machine the sternsof the ramie or othersuitable fibroustplantfrom the table B. Behind these cylinders C C there islocated a breaker composed of two parts D D each part formed withundulations so that the apexes of the nndulations of one part lit intothe corresponding recesses of the other part when the two said parts D Dare brought together; the lower part D of the breaker forms an anvil,bein g fixed on the frame A; the part D is movable and acts as thestriker. This acting part D is connected at its two ends to two verticalbars d d passing through a cross bar E the ends of which latter areguided in vertical slides formed in the frame. The ends of the rods d dare free to slide vertically in the crosspiece E. As the latter islowered it presses on the helical springs l), b with which the lowerends of the rods d d are provided. The same cross bar E is also providedwith two connecting rodsF Fcxtending to a double cranked shaft G whichreceives motion by means of the crank ld on the main first motion shaftH through spur wheel h and pinion g. Behind the breakers D D there aretwo rollers l l of star shaped section so arranged that the arms of onetake into the spaces of the other and have for their object to detachfrom the fibers the woody particles previously broken by the breakers DD.

J J are two receiving cylinders made of caoutchouc or other suitablematerial which receive the liber from which the wood has been removedand convey it onto an endless band K driven by belt le.

Motion isr given to the machine by the crank M provided with a dy wheelor by driving pulleys when steam or other power is employed. The mainshaft H carries a toothed wheel h which as before explained drives thecrank shaft G and in addition to this drives the pinion Z keyed on theshaft L extending across ,the machine; this latter shaft L carries atits other end (Fig. 2) a second pinion Z which is always in gear withboth ofthe pinions c' 11' which are loose on the shafts of rollers I I.'The direction in which it is desired to drive the rollers l l isregulated by means of the hand lever N operating, by means of the rocklever S, suitable clutches Fig. l. These clutches slide on feathers, andbeing alternately thrown in or out of action, lock one or other of thepinions t r1 to the shafts and cause motion. to he given alternately tothe said rollers I I in one direction or the other. ,The speed of therollers l 1 is about sixteen times greater than that of the cylinders CC thus for a turn of the crank M the cylinders C C make a half turn,while the rollers I and l make eight turns. The shaft H also carries apinion receiving a chain o which transmits motion to the groovedcylinders C C and to the caoutchouc receiving cylinders J J.

The action of this machine is as follows: The ramie or other likematerial is placed on IOO the table Bin such manner as to enter beftween the grooved cylinders C C', the cylinder C being mounted onsprings to allow of the introduction of more or less quantity ofmaterial. Upon the material arriving on the anvil D', the woody partsthereof are broken by the acting part D, which by the crank shaft G,has, as before stated, a rapid and contlnuous up and down movementimparted to 1t, the material being crushed between the aforesaidundulating faces of the parts D D'. The fibers together with the brokenwoody parts are then taken between the rollers I I' which at this momentshould be caused to tn rn in the direction indicated by the arrows Fig.4. The arms of the star-section rollers I I' detach the small brokenpieces and allow them to fall below the machine and the fiber arrivesalone to the receiving cylinders J J between which it becomes engaged.As soon as the end or ends of a piece or pieces of the fiber has passedbetween the cylinders J' J', the direction of the movement ofthe rollersI I' is changed, by means of the lever N, prac` tice having shown thatthis second direction is advantageous for avoiding the breaking of thefibers at the knots.

The direction of the motion of rollers I I', indicated by the arrowsFig. 4, is only contlnued upto the moment of the introduction of thetips of the said material between the receiving cylinders J J i, afterwhich the motion of the said rollers I I' is reversed, all as beforedescribed.

The fibers, after the woody matter has been completely removedtherefrom,pass on to the endless band K as has been before explained.

The springs b, b' (Fig. l) with which the ends of the rods cl d' arefurnished' and on which the cross bar E rests are intended to modify theshocks of the striking part D so as not to cause damage whateverquantity of ramie or the like may be introduced into the machine. y

We claiml. A machinefor decorticating ramie Urt/ca utilis) or the likematerial, having a feed table B, two grooved feed rollers C C' betweenwhich the material is passed, a breaking device composed of a lowerlixed part D', undulated on its upper surface,y and a rising and fallingstriking part D also similarly undulated, between which two nndulatedsurfaces, the material is crushed,two rollers II' of star shapedsection, the arms of one of said rollers co-acting with the spaces ofthe other roller, betweenwhich the material passes from the .breakingdevice, a pair of delivery rollers J J to take the material from thestar rollers I I', clutch mechanism S and actuating lever N, forreversing the motion of star rollers I I', as soon as the end of thematerial has been gripped by the delivery rollers J J', thereby freeingthe woody particles from the material, and a traveling band K onto whichthe fiber is delivered by rollers J J as set forth.

2. The combination with a pair of grooved feed rollers C C',and abreaking device composed of a lower xed part D', nndulated on its uppersurface, and a rising and falling striking part D similarly undulated,between which the material is subjected to the crushl ing or breakingaction; of two rollers of star shaped section, the arms of one takinginto the spaces of the other, mechanism for driving same and reversingthe motion when required, and a pair of receiving or delivery rollers JJ substantially as set forth.

In testimony whereof we have hereunto set our hands in the presence ofthe two subscribing witnesses.
